There is no one "best" way to create a kinetic trace. The issues involved and some suggestions are given in the procedure section of the experiment guide. Create an outline of a procedure to use to create a kinetic plot of concentration vs time for the bleaching of a food dye. The outline must contain no more than 10 steps. Make sure to include the glassware and amounts of solutions you expect to use.
